First we have given that,,, speed of Sound =332m/s,,,, Time = 1.45 sec......... , depth let it denoted by d=??,,,,,,, speed of Sound wave = 2×distance /time,........ . . 332 = 2×d/1.45............., 2d=332×1.45,,.. when you solve this you will get 240.7 m and it will be ur ans.. hence,,, the depth of well is 240.7m.
